Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers.

The quest of the absolute leads into the four-dimensional world.

There is no space without aether, and no aether which does not occupy space.

I believe there are 15, 747, 724, 136, 275, 002, 577, 605, 653, 961, 181, 555, 468, 044, 717, 914, 527, 116, 709, 366, 231, 425, 076, 185, 631, 031, 296 protons in the universe and the same number of electrons.

In the most modern theories of physics probability seems to have replaced aether as "the nominative of the verb 'to undulate'."

I ask you to look both ways. For the road to a knowledge of the stars leads through the atom; and important knowledge of the atom has been reached through the stars.

Our ultimate analysis of space leads us not to a "here" and a "there," but to an extension such as that which relates "here" and "there." To put the conclusion rather crudely-space is not a lot of points close together; it is a lot of distances interlocked.
